Bill Gates talks with UC Berkeley professor Dan Portnoy as he tours Portnoy's biology lab. Portnoy's research looks at the listeria bacteria and how the immune system interacts with it, a subject that has implications for vaccine creation.
The tour followed the morning speech that kicked off his three-day college speaking tour.
